IMPROVEMENT IN CUTTER-HEADS FOR MOLDlNGS.

Specification forming part of Letters Patent No. 140,626, dated July 8,1873; application filed December 14, 1872.

T 0 a l whom it may concern:

it known that I, E. H. HINNERS, of the '77, county and State of NewYork, have inwted a new Improy'ement in Gutter-Heads I 1r Molding, ofwhich the following is a speci fixation:

The object of my invention is to produce a rotary cutter-head for makingmoldings with a rabbet at one side, separated from the molding by anarrow strip too thin and weak to sustain the strain to which it wouldbe subject if the rabbet was formed with the ordinary rotaryplaning-cutter; and it consists of a staggered saw attached to thecutter-head of the melding-planer to form the rabbet.

Figure 1 is a side elevation of the cutterllead, such as I propose toemploy, and Fig. 2 is an end elevation.

Similar letters of reference indicate correspondin g parts.

The molding, such as I wish to produce, is shown dotted in section inFig. 1, wherein D represents the rabbet and E the thin strip of wood Iwish to leave between it and the molding. This thin strip would not havestrength to resist the tendency of the cutters to split off from themain portion of the wood if the ordinary planing-cutters were used bothfor the molding and the rabbet, but as the planin g-cutters must be usedfor the mo ding I therefore make a cutter-head for producing this workof a stock, A, with molding-cutters B, anda staggered saw, 0, all asrepresented in the drawing, and thus considerably lesscn thesplitting-strain on the strip E, as the saw has much less of such effectthan the planing-cutters have.

I am aware that similar cutter-heads have been long known to the public,and some pos sessin g many of the general characteristics which are tobe found in mine, but none exhibiting the special feature now disclosedto thepublic by me.

Having thus described my invention, I claim as new and desire to secureby Letters Patent Acutter-head consisting of the molding-cutters B andstaggered saw 0, arranged on the cutter-head A to form a rabbet, I),separated from the molding by a narrow strip, E, substantially asrepresented in the drawing.

E. H. HINNERS.
